Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a detection device and a sample analyzer. Background Technology

[0002] The testing device is used to detect dissolved oxygen and pH in sample water. The device consists of a main body, connector, connecting wire, pH probe, and dissolved oxygen probe. When using the device, the operator starts the main body, then places the pH probe and dissolved oxygen probe on the connecting wire into the water sample cup. The pH probe and dissolved oxygen probe then work to detect the dissolved oxygen and pH in the sample water.

[0003] The inventors discovered in their daily work that when the detection device is in use, the detection probe is placed into the water sample, and after the test is completed, the probe is removed. The surface of the detection probe is covered with water sample. Placing the detection probe directly on the workbench surface will cause contamination and may also affect the accuracy of the detection probe in detecting the next water sample. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in actual use, when the detection probe is placed into a water sample and then removed after testing, the surface of the detection probe will be covered with water sample. This can cause contamination of the workbench surface if the detection probe is placed directly on it, and may also affect the accuracy of the detection probe for the next water sample. Therefore, this invention provides a detection device and sample analyzer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a detection device, comprising a body, a connector fixedly connected to the right end of the body, a connecting wire installed at the right end of the connector, a pH probe fixedly connected to the other end of the connecting wire, a dissolved oxygen probe fixedly connected to the other end of another connecting wire, a cleaning assembly provided at one end of the pH probe and the dissolved oxygen probe, the cleaning assembly comprising a sliding ring slidably connected to the arc surface of the pH probe, an installation ring detachably connected to the inner wall of the sliding ring by means of a disassembly mechanism, a circular sponge fixedly connected to the inner wall of the installation ring, an opening on the front side of the circular sponge, and a driving mechanism for driving the sliding ring to slide and rotate on the arc surface of the pH probe.

[0006] The aforementioned components achieve the following effect: By setting up a cleaning assembly, when using a pH or dissolved oxygen probe for testing, the sliding ring is first moved to the other end by a drive mechanism. Then, the pH or dissolved oxygen probe is placed in the sample water for testing. After the test is completed, the sliding ring is pushed and rotated again by the drive mechanism, causing the circular sponge inside the mounting ring to contact the pH or dissolved oxygen probe, thus cleaning the sample water adhering to the pH or dissolved oxygen probe. After moving the other end of the pH or dissolved oxygen probe, the circular sponge is moved back to contact the other end of the pH or dissolved oxygen probe, and then the circular sponge is rotated to clean the other end of the pH or dissolved oxygen probe. This effectively cleans the sample water adhering to the surface of the pH or dissolved oxygen probe as much as possible, preventing contamination when placed on the countertop and affecting the accuracy of subsequent water samples.

[0007] Preferably, the driving mechanism includes a fixed ring disposed on the arc surface of the pH probe, and multiple evenly distributed connecting strips are slidably inserted into the left end of the fixed ring. A push ring is fixedly connected to the left end of each connecting strip, and the push ring slides on the connecting line. The connecting strips and the sliding ring are fixed.

[0008] The effect achieved by the above components is as follows: when the push ring is manually dragged, the connecting strip on the fixed ring moves, which in turn moves the sliding ring. When the pH probe or dissolved oxygen probe is placed on the table, the connecting strip, the fixed ring, and the sliding ring prevent the pH probe or dissolved oxygen probe from coming into contact with the table and being contaminated.

[0009] Preferably, a fixed circular block is fixedly connected to the left end of the pH probe, and the fixed circular block and the fixed ring are rotatably connected by a bearing.

[0010] The effect achieved by the above components is that by setting a fixed circular block and bearing, the push ring can be manually dragged and rotated at the same time, so that the sliding ring is pushed and rotated at the same time.

[0011] Preferably, the disassembly mechanism includes a pin that is slidably inserted into the inner wall of the sliding ring, the pin being inserted into the mounting ring.

[0012] The effect achieved by the above components is as follows: after cleaning the pH probe or dissolved oxygen probe, the pull mechanism completely separates the pin from the mounting ring, compressing the elastic mechanism, then the circular sponge is removed, and a new circular sponge is replaced. The pull mechanism is then released, the elastic mechanism resets, and the pin is inserted into the mounting ring, thus completing the replacement of the new circular sponge and preventing the cleaned circular sponge from contaminating the pH probe or dissolved oxygen probe.

[0013] Preferably, a pull rope is fixedly connected to the left end of the pin, and the pull rope passes through the sliding ring.

[0014] The effect achieved by the above components is that pulling the pull rope completely separates the pin from the mounting ring.

[0015] Preferably, a spring is fixedly connected to the left end of the pin, and the other end of the spring is fixed to the sliding ring.

[0016] The effect achieved by the above components is that pulling the cord completely separates the pin from the mounting ring, thereby compressing the spring.

[0017] Preferably, the arc surface of the push ring is provided with a plurality of evenly distributed anti-slip protrusions.

[0018] The effect achieved by the above components is to increase the friction between the push ring and the user's fingers by setting anti-slip protrusions.

[0019] A sample analyzer includes a detection device, wherein the detection device is any one of the detection devices described above.

[0020] The effect achieved by the above components is that the sample analyzer can detect and analyze multiple physical indicators of water samples, such as turbidity and conductivity.

[0021] In summary, the beneficial effects of this utility model are as follows: In this invention, by setting up a cleaning component, when using a pH probe or dissolved oxygen probe for testing, the sliding ring is first moved to the other end by a driving mechanism. Then, the pH probe or dissolved oxygen probe is placed on the sample water for testing. After the test is completed, the sliding ring is pushed and rotated again by the driving mechanism, so that the circular sponge inside the mounting ring contacts the pH probe or dissolved oxygen probe, thus cleaning the sample water adhering to the pH probe or dissolved oxygen probe. After moving the other end of the pH probe or dissolved oxygen probe, the circular sponge is moved back to contact the other end of the pH probe or dissolved oxygen probe, and then the circular sponge is rotated to clean the other end of the pH probe or dissolved oxygen probe. This effectively cleans the sample water adhering to the surface of the pH probe or dissolved oxygen probe as much as possible, preventing contamination when placed on the table and affecting the accuracy of subsequent water samples.

[0025] Reference Figure 2As shown in this embodiment: the cleaning component 2 includes a sliding ring 21 slidably connected to the arc surface of the pH probe 6. The inner wall of the sliding ring 21 is provided with a mounting ring 22 that can be detachably connected via a disassembly mechanism 3. A circular sponge 23 is fixedly connected to the inner wall of the mounting ring 22. An opening 24 is provided on the front of the circular sponge 23. The arc surface of the pH probe 6 is provided with a driving mechanism 25 for driving the sliding ring 21 to slide and rotate. By setting the cleaning component 2, when using the pH probe 6 or dissolved oxygen probe 7 for detection, the driving mechanism 25 is used to move the sliding ring 21 to the other end. Then, the pH probe 6 or dissolved oxygen probe 7 is placed in the sample water for testing. After the test is completed, the sliding ring 21 is pushed and rotated again by the drive mechanism 25, so that the circular sponge 23 inside the mounting ring 22 comes into contact with the pH probe 6 or dissolved oxygen probe 7, thus cleaning the sample water adhering to the pH probe 6 or dissolved oxygen probe 7. After moving the other end of the pH probe 6 or dissolved oxygen probe 7, the circular sponge 23 is moved back to contact the other end of the pH probe 6 or dissolved oxygen probe 7, and then the circular sponge 23 is rotated to clean the pH probe. 6 or the other end of the dissolved oxygen probe 7, thereby cleaning the sample water adhering to the surface of the pH probe 6 or dissolved oxygen probe 7 as much as possible, avoiding contamination when placed on the table and affecting the accuracy of the next water sample. The driving mechanism 25 includes a fixing ring 251 set on the arc surface of the pH probe 6. Multiple evenly distributed connecting strips 252 are slidably inserted into the left end of the fixing ring 251. A push ring 253 is fixedly connected to the left end of the connecting strips 252. The push ring 253 slides on the connecting line 5. The connecting strips 252 and the sliding ring 21 are fixed. The push ring 253 is manually dragged so that the fixing ring The connecting strip 252 on 251 moves, causing the sliding ring 21 to move. When the pH probe 6 or dissolved oxygen probe 7 is placed on the table, the connecting strip 252, the fixing ring 251, and the sliding ring 21 prevent the pH probe 6 or dissolved oxygen probe 7 from contacting the table and being contaminated. The left end of the pH probe 6 is fixedly connected to a fixing block 254. The fixing block 254 and the fixing ring 251 are rotatably connected by a bearing 255. By setting the fixing block 254 and the bearing 255, the push ring 253 can be manually dragged and rotated at the same time, so that the sliding ring 21 is pushed and rotated at the same time.

[0026] Reference Figure 3As shown in this embodiment: the disassembly mechanism 3 includes a pin 31 that slides into the inner wall of the sliding ring 21. The pin 31 is inserted into the mounting ring 22. After cleaning the pH probe 6 or dissolved oxygen probe 7, the pin 31 is completely separated from the mounting ring 22 by the pulling mechanism, which compresses the elastic mechanism. Then, the circular sponge 23 is disassembled, and a new circular sponge 23 is replaced. The pulling mechanism is then released, the elastic mechanism resets, and the pin 31 is inserted into the mounting ring 22, thus completing the replacement of the new circular sponge 23. This prevents the cleaned circular sponge 23 from contaminating the pH probe 6 or dissolved oxygen probe 7. The left end of the pin 31 is fixed. A pull rope 33 is fixedly connected to the sliding ring 21. Pulling the pull rope 33 completely separates the pin 31 from the mounting ring 22. A spring 32 is fixedly connected to the left end of the pin 31. The other end of the spring 32 is fixed to the sliding ring 21. Pulling the pull rope 33 completely separates the pin 31 from the mounting ring 22, compressing the spring 32. The arc surface of the push ring 253 is provided with multiple evenly distributed anti-slip protrusions. By providing anti-slip protrusions, the friction between the push ring 253 and the user's fingers is increased. The detection device is a detection device. The sample analyzer can detect and analyze multiple physical indicators of water samples, such as turbidity and conductivity.

[0027] Working principle: When using the testing device, the operator starts the main unit 1, then places the pH probe 6 (model YPS08) and dissolved oxygen probe 7 (model JXBS-3001-YG) from the connecting wire 5 on the connector 4 into the water sample cup. The pH probe 6 and dissolved oxygen probe 7 then operate to detect the dissolved oxygen and pH of the sample water. When using either the pH probe 6 or the dissolved oxygen probe 7, manually drag the push ring 253 to move the connecting strip 252 on the fixed ring 251, causing the sliding ring 21 to move to the other end. Then, the P... After placing the pH probe 6 or dissolved oxygen probe 7 in the water sample for testing, manually drag and rotate the push ring 253 again. This pushes and rotates the sliding ring 21, causing the circular sponge 23 inside the mounting ring 22 to contact the pH probe 6 or dissolved oxygen probe 7, thus cleaning the sample water adhering to the pH probe 6 or dissolved oxygen probe 7. After moving the other end of the pH probe 6 or dissolved oxygen probe 7, move the circular sponge 23 back to contact the other end of the pH probe 6 or dissolved oxygen probe 7, and then rotate the circular sponge 23 to clean the sample water. Clean the other end of the pH probe 6 or dissolved oxygen probe 7 to remove as much sample water as possible from their surface, preventing contamination and ensuring the accuracy of subsequent water samples. After cleaning, pull the cord 33 to completely separate the pin 31 from the mounting ring 22, compressing the spring 32. Then, remove the circular sponge 23, replace it with a new one, release the cord 33, return the spring 32 to its original position, and insert the pin 31 into the mounting ring 22. Replace the circular sponge 23 to prevent the cleaned sponge 23 from contaminating the pH probe 6 or dissolved oxygen probe 7. When placing the pH probe 6 or dissolved oxygen probe 7 on the table, use the connecting strip 252, fixing ring 251, and sliding ring 21 to prevent the pH probe 6 or dissolved oxygen probe 7 from contacting the table and becoming contaminated. By setting anti-slip protrusions, the friction between the push ring 253 and the user's fingers is increased. The sample analyzer (model RH2065 water quality analyzer can be selected) can detect and analyze multiple physical indicators of water samples, such as turbidity and conductivity.
